I use to be on the Depo shot, but stopped taking it about four to five months ago. I usually get my period anywhere from the 21st to the 1st every month. My last one was from March 1st to March 6th. It's now April 18th and I still haven't gotten my period for the month. I have sex with the same person every weekend, and we're usually drunk so I'm not really sure if he pulls out in time. I know this sounds irresponsible. Could my missed period be due to my body still coming off of the birth control, or is it possible that I am pregnant? I took a pregnancy test on the 12th of last month, but I figured that would be too early to know anyways. I haven't had any period cramps, but I have had sharp pains in my stomach occasionally. Please help!
